This Court granted certiorari to the Court of Appeals in Common Cause/Georgia v. Campbell, 268 Ga. App. 599 (602 SE2d 333) (2004), to determine if the Court of Appeals erred in affirming the trial court’s dismissal of the complaint for failure to state a claim upon which relief could be granted. Finding that the dismissal was proper, we affirm.
In 1999, the City of Atlanta (“City”) opened bidding for a five-year contract to manage parking lots at then Hartsfield Atlanta International Airport. Parking Company of America (“PCOA”), which was already managing airport parking under an existing contract, submitted the low bid of $465,000 per year; its existing contract was for $697,000 per year. On November 20, 2000, the City passed a resolution that “an appropriate agreement” be entered into with PCOA (described as “the recommended operator”), and directed that the Director of the Bureau of Purchasing and Real Estate prepare such an agreement, which was to be approved as to form by the City Attorney and executed by the Mayor. The resolution specifically *481stated that the agreement would not be binding on the City until executed by the Mayor and delivered to PCOA. Mayor Campbell, however, did not sign a new contract until January 8, 2002. In the interim, PCOA was paid at the higher rate under the existing contract, and received approximately $300,000 more than it would have under the new rate.
Common Cause and Elizabeth Hale Barnett (collectively “Common Cause”) brought suit on behalf of the City and its taxpayers seeking a judgment against Campbell individually for the approximately $300,000. Campbell moved to dismiss the suit pursuant to OCGA § 9-11-12 (b) (6).1 The trial court granted the motion and the Court of Appeals affirmed. Further facts can be found in the opinion of the Court of Appeals. See Common Cause/Georgia, supra.
A motion to dismiss brought under OCGA § 9-11-12 (b) (6) for failure to state a claim upon which relief can be granted should be granted only when:
the allegations of the complaint disclose with certainty that the claimant would not be entitled to relief under any state of provable facts asserted in support thereof; [cit.] and... the movant establishes that the claimant could not possibly introduce evidence within the framework of the complaint sufficient to warrant a grant of the relief sought. [Cit.]
Anderson v. Flake, 267 Ga. 498, 501 (2) (480 SE2d 10) (1997).
Common Cause contends that there are two separate cognizable claims advanced in its complaint. However, relief cannot be granted on either of the advanced claims.
1. Common Cause asserts that a taxpayer citizen of a Georgia municipality has the power to sue, in the name of that municipality, an officer of the municipality, in the same manner that a corporate shareholder may sue a corporate officer in a derivative action. See OCGA § 14-2-831. As the Court of Appeals correctly noted, there is no basis in Georgia law for such an action. Common Cause/Georgia, supra at 600 (1). Municipal corporations are creatures of the State, see Dept. of Transp. v. City of Atlanta, 255 Ga. 124, 130 (3) (337 SE2d 327) (1985), and it is for the General Assembly to specify any such power to sue on the part of taxpayers.
2. This Court recognized in Koehler v. Massed, 229 Ga. 359 (191 SE2d 830) (1972), that, in certain circumstances, a taxpayer may pursue a claim for damages against government officials in their *482individual capacities, in a class action and on behalf of the municipality. However, the scope of that 1972 decision has been necessarily circumscribed by a 1991 amendment to the State Constitution. See Ga. Const. of 1983, Art. I, Sec. II, Par. IX (d); Cameron v. Lang, 274 Ga. 122, 123-126 (1)-(2) (549 SE2d 341) (2001); Gilbert v. Richardson, 264 Ga. 744, 746-751 (2)-(4) (452 SE2d 476) (1994). The amendment applies to questions concerning the personal liability of municipal officers. See Cameron, supra; Kidd v. Coates, 271 Ga. 33 (518 SE2d 124) (1999). Under the amendment, Campbell could be liable only if he negligently performed, or failed to perform, a ministerial duty, or acted “with actual malice or with actual intent to cause injury....” Ga. Const, of 1983, Art. I, Sec. II, Par. IX (d); Cameron, supra. He had immunity for the negligent performance of a discretionary duty. Cameron, supra at 124 (2).
Common Cause does not assert that Campbell acted with actual malice or actual intent to cause injury, and thus, its complaint only states a cognizable claim if the duty allegedly breached was a ministerial one, see Ga. Const. of 1983, Art. I, Sec. II, Par. IX (d); Cameron, supra at 123 (1), which is what Common Cause asserts. “Generally, a discretionary act is one that requires the examination of facts and the exercise of considered judgment before deciding on a course of action, whereas a ministerial act is one that is a mandatory fixed obligation for which mandamus will lie to compel performance.” (Citations omitted.) Henderman v. Walton County &c. Auth., 271 Ga. 192, 193 (2) (515 SE2d 617) (1999).
A ministerial act is commonly one that is simple, absolute, and definite, arising under conditions admitted or proved to exist, and requiring merely the execution of a specific duty. A discretionary act, however, calls for the exercise of personal deliberation and judgment, which in turn entails examining the facts, reaching reasoned conclusions, and acting on them in a way not specifically directed.
Standard v. Hobbs, 263 Ga. App. 873, 875 (1) (589 SE2d 634) (2003).
In the complaint, Common Cause contends that Campbell had a ministerial duty to execute a contract.2 However, thé City ordinance upon which it relies, City Code § 2-176, specifies that the Mayor is to execute a contract within 30 days of the resolution authorizing a contract, or inform the President of the City Council, in writing, the *483reasons why the Mayor has not executed a contract. Clearly, on its face, the ordinance gives the Mayor the choice to sign or not to sign a prepared contract, and he does not have the specific duty to execute a contract. Accordingly, the failure to execute a contract is not a violation of a ministerial duty, but rather an act of discretion. Common Cause also asserts that Campbell did not report to the President of the City Council his reasons for not signing a contract within 30 days of the resolution. But, even assuming that the failure to follow through on that alternative action is considered a breach of a ministerial duty, Common Cause does not assert that any damages to the City flowed from that failure, only from the failure to pursue the other course of action available under the ordinance and execute a contract within 30 days of the resolution.
Further, prior to Campbell’s execution of the contract on January 8, 2002, Common Cause could not have successfully sought a writ of mandamus to compel him to execute a contract. Campbell was certainly authorized to sign a contract after the November 20, 2000 resolution, but that is insufficient: “ ‘[t]he law must not only authorize the act be done, but must require its performance.’ ” Jennings v. McIntosh County Bd. of Commrs., 276 Ga. 842, 844(1) (583 SE2d 839) (2003). See also Hartsfield v. Salem, 213 Ga. 760 (1) (101 SE2d 701) (1958). While a petition for a writ of mandamus to compel Campbell to either execute a contract or inform the President of the City Council in writing why he had not done so might have been successful, it does not follow that the act of executing a contract is ministerial; there was another course of action open to Campbell.
The motion to dismiss established that the complaint disclosed that Common Cause would not be able to demonstrate the right to the requested relief. Accordingly, the motion was properly granted.
Judgment affirmed.
All the Justices concur, except Fletcher, C. J., who dissents.The City also moved to dismiss itself as an involuntary plaintiff, contending that there was no basis for joining it as such under OCGA § 9-11-19. This motion was also granted.
We note that there is no allegation that a contract was ever prepared by the Director of the Bureau of Purchasing and Real Estate for Campbell’s signature, and approved as to form by the City Attorney, as specified in the resolution authorizing Campbell to execute a contract with the recommended operator.
